| 中文摘要: |
| 粤西—桂东南毗邻区是重要的剪切带型金成矿带。在黄泥坑—丰木地区近年来新发现了黄泥坑大型剪切带型金矿床，以及一大批具有良好的资源找矿潜力的金矿点和化探异常。为快速实现该地区金找矿远景区的圈定，本文通过对以往地质勘查项目及区域地质成果资料分析，总结了黄泥坑—丰木地区剪切带型金矿床的地质特征、控矿因素，认为该地区金成矿过程受地层、构造、岩浆岩多重因素控制，较为独特的矿化特征是区内花岗闪长岩体接触带也形成了剪切带型金矿体。通过对黄泥坑—丰木地区成矿地质条件、控矿因素以及化探异常特征进行综合研究分析，提出了该地区周边4个有利的金找矿靶区，即花山、西牛坑、先锋顶、罗密4处找矿靶区，为新一轮找矿突破战略行动奠定良好基础。 |
| 英文摘要: |
| The adjacent area of West Guangdong-Southeast Guangxi is an important metallogenic belt shear zone type gold deposist. A large shear zone type gold deposit has been discovered in Huangnikeng-Fengmu area in recent years， and a large number of gold occurrences and geochemical anomalies with prospecting potential have been discovered. In order to quickly delineate gold perspective areas in this area， the geological characteristics and ore-controlling factors of the shear zone type gold deposit in Huangnikeng-Fengmu area are summarized in this paper， through the analysis of previous exploration projects and regional geological achievements， and it is considered that the gold mineralization process in this area is controlled by strata， structure， and magmatic rocks. The more unique mineralization feature is that the shear zone type gold ore body is also formed in the contact zone of granodiorite mass in the area. Based on the comprehensive study and analysis of metallogenic geological conditions， ore-controlling factors and geochemical anomaly characteristics in Huangnikeng-Fengmu area， four favorable gold prospecting target areas around the area are proposed， including Huashan area， Xiniukeng area， Xianfengding area and Luomi area. It lays a good foundation for a new round of prospecting breakthrough strategic action. |
